/**
 * 核心原理
 * 1）、@EnableRedisHttpSession导入RedisHttpSessionConfiguration配置
 *      1、给容器中添加了一个组件
 *         SessionRepository=>>> RedisOperationsSessionRepository：Redis操作session，session的增删改查封装类
 *      2、SessionRepositorvFilter== > Filter:session，存储过滤器，每个请求过来都必须经过filter
 *          1、创建的时候，就自动从容器中获取到了sessionRepository;
 *          2、原始的request，response都被包装。SessionRepositoryRequestWrapper， SessionRepositoryResponse
 *          3、以后获取session。request,getSession();
 *          4、wrappedRequest,getSession();===> SessionRepository 中获取到的。
